This is an improved insert for the game, Tiwanaku, published by Sit Down! The game is beautifully made but they put very little effort into the insert for it.

Please note that the picture shows the first versions for pieces 1 and 2, I updated piece 1 to give you room to be able to reach down and grab scenario disks and the Pachamama wheel without needing to turn the insert upside down. Piece 2 is updated to be able to grab any set of tiles without having to remove other tiles first and it will use less filament.
